# bogolexer(1)

Utility program for separating email messages into tokens

## NAME

bogolexer - Utility program for separating email messages into tokens

## SYNOPSIS

**bogolexer** \[-p\] \[-q\] \[-h\] \[-n\] \[-v\] \[-x *flags*\] \[-c *file*\] \[-C\] \[-D\] \[-I *file*\] \[-O *file*\] \[-V\]

## DESCRIPTION

Bogolexer is part of the bogofilter Bayesian spam filter package.

It is used to separate messages into tokens and to test new versions of the lexer.l code.

## OPTIONS

The **-p** option tells bogolexer to print just the tokens read from stdin, without any extra messages.

The **-q** option tells bogolexer to print a token count, without printing the actual tokens.

The **-h** option prints the help message and exits.

The **-n** option tells bogolexer to map non-ascii characters to the question point '?'.

The **-v** option increases the verbosity level.

The **-x** *flags* option allows setting of debug flags for printing debug messages.

The **-c***filename* option tells bogolexer to read the config file named.

The **-C** option prevents bogolexer from reading configuration files.

The **-D** option redirects the debugging output to stdout (it defaults to stderr).

The **-I** *filename* option tells bogolexer to read its input from the specified file, rather than from *stdin*.

The **-O** *filename* option tells bogolexer to write its output to the specified file, rather than to *stdout*.

The **-V** option prints the version number and exits.
